l "f invention relates to'cer'tain improvements in driers of the typeinnf'hich-thevma- `terial is mounted on trucks.

The invention is iartvicnlarl adanted :tor

y L l l u u n opening-in theA drier, While thenend-8m1s dryilflgarticles such as hats', but it -will'be understood that the inventioncanbe used for dryingother articles without departing from the essentialfeatures oi the invention r One object of the invention is to provide adrierinwhichithere are two trucks, so that one can be loaded whileV theother is in the` drying chamber. A further object ot the vinvention isto so construct the trucks thatwhen one is within the drying chamber,the ends of the truck will close both ends of said chamber, dispensingwith the independent doors for the drier. A still further obj ect of theinvention is to so design the truck that the poles forsupportingthe hatsmay be hung from overhead Referring to the drawings, 1V is a drierwhich'is substantially the length of one `cgt the trucks 2. The casingof the drier en closes a drying chamber and two circulating' chambers inthe present instance. The Y drawings show a double drier having a widedrying'chamber and two tracks, with two trucks for each track, but 'itwillbe understood that a drier having a single track may be used in someinstances. I Y

, The rails V3 of thetracks extend through the drying chamber and beyondeach end of the drier as shown, so as to support a truck being loaded orunloaded. The rails are arranged overhead in the present instance, and

have stop bars 18 attheir outer ends which connect the rails, the trucksbeing suspended from the rails. l Each truck has axles 6 mounted insuitable bearings, and on each axle is a flanged wheel 5, which travelson the rails of the erack. Y

end sections 7 and 8, which close the endsfof the drying'chamber when atruck `1s within he chamber. The-cnd7 snugly tits the-end larger thanthe openingfand tits against .thel

.rrainannnrnra rnnnsYLvanrA, 1A- -connona- Each truck is'closed ateachend bysolid endfoi .thel drier land acts as stop orffthe dryingchambery- By this arrangement, no s doors are required V.tor vthe dryingv chamber, as the two ends ot the truck closeV the drying chambersutlicientlyjto prevent vthe escape ofV `the air in circulation.

Each truck is made in the torni of a skeleton trame L The end sections 7and 8 of the truck are suspended from the frame i and are connected vattheir lower ends by rods 17. A series of barst) extend across the trame'l from which the poles 10 kare suspended..v j

Each pole in the presentfinstanceis madeas shown in Fig. 6, and has ahook 11 which is shaped to engage oneot the cross-bars 9, whileprojecting from the pole are aseries of diage' V onal pegs 12 on whichthe hats are mounted.

Thesepegs may have enlarged ends, as shown i in Fig. 6,-covered withfelt or other suitable materialit found desirable.

.At each side'of the drying chambers are circulating chambers 13,` andlocated in the chambers in theppresent instance are circulating fans 14,the casings of which are made as shown in Fig. 2. These fans are'drivenby beltingftrom a motor 15. y In the present inl stance there areltwofans ateach side'of the drying chamber and an independent motor driveseach pair ottans. 16 are heating coils located inthe circulating chamberand are arranged to heat the air in'circulation.

The operationis as follows z-When' one of the trucks is on the rails atone side. ot the drier, the hats are placed on the poles 10 and the`poles are hung from the cross-bars 6.V

When the truck is loaded with polesand the v hats on thefother truckwithin the drierhave been. dried, and are ready to be removed, the truckWithin the drier is withdrawn from the drying chamber and the othertruck carryico i ing the hats to vbe dried is run into the drying ichamber, the two ends of the truck'closing theI drying chamber. Thelargeend ofthe truc-kalso acts as a stop'to locate the truck within thedrier, the drier being closedatboth ends,

' and -wherea double drieris used as in Fig. 1, vtwo trucks are locatedsideby side within the drying chamber of the drier. heated air'inoiroulation will dry the hats or other ar- Y Y p Ving chamber; acirculating chamber at each V`tieles suspended from the bars of thetrucks.

A drier of this type occupies very little floor space. The` trucks canbe readily loaded and'unloaded While the articles on the. other truckare being dried.

I claim: f

1. The combination in a drier having a dry ing chamber means forolrculating heated air in the drying chamber; tWo overhead rails eX-tending through the drying chamber and be# yond each end thereof; andtWo independent trucks mounted on the rails, said trucks havingmeans byWhioh material to be dried is suspended therefrom, each truck havingsolid ends; one end beinglarger than the other so 2. The combination ina drier having a dryside of the drying chamber; means for circulatingair in said chambers; overhead rails Y extending through the dryingchamber and f ,trucks having closed ends, one end of each truck beinglarger than the opposite end7 the smaller end extending Within theopening of the drying chamber and the larger end resting against the endof the drying chamber When the truck is Within the said chamber;

`a series of cross-bars on eaeh truck; hooked poles arranged to engage.the cross-bars and to be suspended therefrom; and pegs on the poles onWhich articles to be dried ar mounted.
